I'm a laser boy myself, but mainly because I like how it looks i battle viewer. Lasers miss too, as do missiles. The accuracy brings the range and DPM differences together, making a fairly balanced approach to the game.
Yeah, at the high end Singularity Drivers have much less DPM (taking accuracy into account as well), however you have to kinetic defenses into consideration. Armor has a terrible defense/mass ratio compared to shields. Hence, it makes sense on offense that beams have a higher dpm/mass ratio. IMO its pretty balanced, with the only exception of durantium being such a huge in game resource, and Durantium Drivers pretty much matching the high end singularity drivers.
I Have no idea why the devs dont have all resources balanced by DEFAULT. From an offense and defensive weapons point of view, they pretty much all have the same type of module support abilities. They all have social building uses as well. It would make it interesting IMO, as your strategy would GREATLY change based on the resources available. Hence, playing same maps size, same race, same opponents, you would be forced to play differently because of resources.
